Introduction: Awesome Homemade Door Bell
This door bell is great for your room, and only costs three bucks! This is my 1st instructable, so I hope you enjoy!
ps there is NO SOLDERING REQUIRED!
i would really appreciate it if you would comment and tell me how I could make it better!
Step 1: What You Need
Okay, here is what you will need:
1. 2 strips of sheet metal
2. a red wire and a black one
3. 9V battery
4. rubber bands
5. small square of cardboard
6. 6VDC Mini Buzzer (like three buck from radio shack)
7. Duct Tape
8. Thumbtack or somthin else with a small sharp point(not pictured)
Step 2: The Base
Cut the cardboard in half. Use one half to cut out a small strip of cardboard that is the same width of the smaller peice of metal, but smaller in length.
poke a hole using the thumbtack in the end of the smaller peice of metal.
tape the strip of cardboard to the bottom of the metal peice, then twist the black wire through the hole in the matal so it stays. tape it to one of the half peice of cardboard.
Step 3: The Button
Now for the button.
poke the hole and thread the black wire leading to the buzzer through the longer metal peice.
bend it into the shape below. tape the other half of the cardboard to the top.
Step 4: Base+Button
Now, glue the button onto the base so that the metal peices are a hair's breadth apart.
the picture below might help.
note*: i messed up at first in the picture: the red wire on the left should be black.
Step 5: The Power Source
now you have to attach the black wire that is from the base to the battery
then attach the red wire you havent used yet to the battery!
when attaching wires to the battery, first make sure that the red wire is on the smaller hole sticking out of the top of the battery(positive side) and the black one is on the bigger hole(the negative side)
you might have to wrap rubber bands around it so the wires are securely connected!
Step 6: The Final Connection!
twist to gether the red wire from the battery and the red wire from the buzzer! the finished product should look like so:
Step 7: Installation!!!!
Now it's time to install the doorbell! Just put the button part on the front of the door, and put the battery and the buzzer on the side of the door facing your room!
you should duct tape the wires to the door like I did
The first picture is of the outside of the door, the second is the inside.
Step 8: All Done!!!!!!
You are done with your doorbell! just add a sign and admire your handywork!
